Throughout the day on Monday (and now TuesdayWednesday Thursday FridaySaturday!) week news and rumors will be flying about job security of various NFL coaches. Bookmark this page to stay updated constantly.

Although Ray Horton realizes that Jeff Fisher has to be the No. 1 choice for the Rams job, the St. Louis Post Dispatch is reporting that if Fisher takes the Miami job, St. Louis will give a second look to Horton, the Cardinals defensive coordinator. Apparently, Horton's initial five-hour interview went very well. "When it was over they called my agent and said they were blown away by him, and he couldn't have been any better," Horton said.

According to Rapid Reporter Ron Clements, the Rams have received permission to interview Tennessee VP of football operations Lake Dawson and Titans VP of player personnel Ruston Webster for the vacant GM job. Both worked with Jeff Fisher in Tennessee.

The Chiefs reportedly have decided to remove the interim tag for coach Romeo Crennel, meaning the job is all his. It seems like general manager Scott Pioli wanted Crennel to have the job all along.

It didn't take long for the Patriots to hire their next offensive coordinator to replace Bill O'Brien. It's their old offensive coordinator of course as Josh McDaniels will take over O'Brien's spot for 2012 AND will begin work immediately, helping New England in this postseason.

According to NFL.com's Jason La Canfora, the Dolphins have permission from the Falcons to interview offensive coordinator Mike Mularkey. Jacksonville already has shown interest in Mularkey.

Packers offensive coordinator Joe Philbin has been a busy man lately, according to the Milwaukee Journal Sentinel. Philben was in Kansas City on Wednesday, and by this weekend, he'll interview for the Dolphins head coaching job as well.

1:20 p.m. ET

Although he and general manager A.J. Smith kept their job, Chargers coach Norv Turner fired defensive coordinator Greg Manusky after just one season. Interesting, because, three days ago, Turner said he thought Manusky had done a good job this year.

9:00 a.m. ET

Raheem Morris was spotted dining with Redskins brass, and Washington could be interested in hiring Morris as a defensive coach. The only problem with that scenario is that Buccaneers were the worst team in the league in points allowed this season.

Yahoo Sports' Michael Silver has written that the Jeff Fisher sweepstakes has become a two-way race between the Dolphins and the Rams. Fisher was scheduled to interview with St. Louis today.

NFL.com's Albert Breer is saying that Jay (not Jon!) Gruden is the favorite to land the head coaching job in Jacksonville. The Bengals offensive coordinator, however, can't interview until Cincinnati is out of the playoffs. Until then, it sounds like the Jaguars will continue to interview every hot offensive coordinator they can find.

WEDNESDAY

8:20 p.m. ET

According to multiple reports, Patriots offensive coordinator Bill O'Brien will interview for the Penn State job on Thursday. Though his interview with the school has been reported and then denied previously, it seems like O'Brien might have a real shot at landing this position, especially since it appears he's not a candidate for any current open NFL head coaching jobs.

5:58 p.m. ET

The Rams have requested permission from the Ravens to interview director of player personnel Eric DeCosta for the St. Louis general manager spot, according to PFT. DeCosta is seen as the possible successor to Ozzie Newsome in Baltimore. St. Louis also has received permission from the Falcons to interview director of player personnel Les Snead.

Colts owner Jim Irsay calls firing Bill and Chris Polian a tough decision, and adds that "it's not outside the realm of possibility" that Jim Caldwell returns as head coach. When asked if Peyton Manning will play again he responded, "I don't."

Although there were reports that Patriots offensive coordinator Bill O'Brien was the prime coaching target for Penn State, it sounds like O'Brien won't be headed to Happy Valley after all.

12:45 p.m. ET

During his last regular-season news conference, Colts coach Jim Caldwell said he's "moving forward" with his day-to-day work. Caldwell also said he met with owner Jim Irsay on Sunday night and with executives Bill and Chris Polian on Monday morning. Obviously, at this moment, Caldwell is still employed. Which led Indy Star reporter Phillip B. Wilson to tweet, "Colts fans, to be honest, I have no idea what's going on ... maybe team won't announce changes for another day or two, IDK."

An interesting set of tweets from UniversalDraft.com's Chris Kouffman: "<s>@</s>ArmandoSalguero with a stunning revelation that Carl Peterson was told to have dinner w/ Jon Gruden and allowed to offer Gruden the job ... which included total control over football operations, ability to hire and fire whomever he wanted...and Gruden TURNED IT DOWN. Yikes."

The Dolphins release a statement saying they're gearing up for their coaching search.

We have our first victim on Black Monday! Steve Spagnuolo, as expected, was fired by the St. Louis on Monday. Spags was 10-38 in three years with the Rams but should be a hot name for defensive coordinator positions.

You want to talk about a coach in demand? How about Jeff Fisher. Mike Freeman writes that the two jobs that intrigue him the most are Indianapolis and Tampa Bay.

9:39 a.m. ET

Speaking of the Jets, their public relations staff announced that BOTH general manager Mike Tannenbaum and coach Rex Ryan will be at Monday's press conference. That's not "normal" and it could mean that people's jobs are in trouble.

Despite a disappointing season in which the Jets didn't make the playoffs, defensive coordinator Mike Pettine -- whose reputation has largely remained intact this year -- has reportedly drawn interest from the Dolphins.

CBSSports.com's Mike Freeman reports that the Bucs spent all evening gathering intel on Raheem Morris from players. Ownership is starting to believe that though they don't want to fire Morris, they might have to fire Morris.
